Of His Blood and Bone

If upon reaching the end of the For Temeria! story quest you decide that it makes sense to join Vernon Roche in search of Dethmold and Anais rather than seeking out Triss, then you can head to the edge of the market square and descend through the hole in the floor to arrive at the sewers. You'll head to a guarded gate, where you can use a sign to distract the guards long enough that they are overwhelmed. As you start through the gate they were guarding, the quest is activated.

(LEFT) 'Head through the tunnels with Vernon Roche as you make your way toward the Kaedweni camp.' (RIGHT) 'You will do battle with many soldiers on your way to confront Dethmold.'

Proceed up the tunnel and a scene follows. Roche makes his way to a high wall after killing two guards with your assistance. He states that he will take the high road, which means you are left alone to follow the low road to your left. There, some soldiers will rush you. Tend to them in the usual manner while dodging magical bursts fired by a sorcerer who stands on a nearby ledge.

When you defeat the soldiers, the sorcerer will teleport out of sight. You will need to kill still more soldiers that arrive. They're tougher than the last lot, but still shouldn't pose a true threat. Defeat them, then head left again toward the wall where Roche is now pacing. He has opened a gate for you, so pass through it and you'll find a courtyard flooded with soldiers. For the most part, you will have to deal with these men alone. The sorcerer has also returned, so you'll have to worry about his fiery blasts as you defeat his men.

As you take out a number of the men, Roche will work his way toward you and eventually join the fray. Now the two of you can dispose of the last of the soldiers and then it's time to deal with the sorcerer. He teleports around the area, making a nuisance of himself and preventing you from taking care of him in a single flurry of slashes, but you can move around the area. Follow him to where he reappears, hit him a few times and then repeat as necessary. Once you fell the sorcerer, the camera pans to show a path descending into a lower area.

(LEFT) 'Get the key from Dethmold's corpse and search the safe to find a truly powerful steel blade.' (RIGHT) 'You can impact what Roche decides to do with Anais, now that she has been rescued.'

Start in that direction and at the base, you'll see Anais behind a barrier. There's a door to the left, as well. Start in that direction and a scene will follow. Dethmold meets a messy end. You can search his corpse and find a key to the safe, which you should open to obtain the powerful Forgotten Vran Sword, a steel weapon capable of tremendous damage.

Now backtrack and find Anais. You can give Roche reason to doubt King Radovid, or you can agree that it's best to hand the girl over to him.

If you talk Roche into handing Anais over to the Timerians, you'll head back up the stairs with Roche and the girl. You'll soon come into a group of Knights of the Order. After a short conversation, you'll have to fight them. When you win, you can escort Anais back toward the market square. Despite the indicator on the map, which points sharply to your right, you should head along the route that you followed as you initially worked through this quest. It's the only one that will take you to your destination. As you arrive, the quest concludes.

If you instead agree with Roche that he should hand Anais over to Radovid, you'll head up into the courtyard and meet with the Knights of the Order, just as you would in the other scenario. However, you won't have to fight them. Instead, they'll help you escort Anais back toward camp. As you near your destination, the quest concludes.
